Title: Improvements in or relating to a speed governor control system for an engine
IPC: F02D25/00
Filed: 1947-06-03
Abstract: 646,142. Speed governors. NORDBERG MANUFACTURING CO. June 3, 1947, No. 14678. Convention date, Dec. 27, 1943. [Class 57] A control system for an engine which transmits power through a torque transmitter of the dynamic reaction type comprises a speed governor which controls the energy input to the engine and has different speed ranges corresponding to idling and loaded conditions means being provided for concurrently setting the governor to the loaded range when the torque transmitter is energized and to the idling range at other times. The setting means may comprise solenoids 45, 46, Fig. 3, which are energized together with a dynamo-electric type clutch 65 and which raise a link 42 to increase the loading of the governor spring 19. The governor, Fig. 2, has a pair of pivoted weights 15 loaded by spring 19 which abuts a seat 23 slidable in a tube 22 and having a stem 24 projecting through a slot 25 in the wall of the tube. A screw stop 26 limits the upward movement of the seat and may be adjusted to vary the idling speed. The lower end of the seat 25 limits the lower position of the spring seat and thus limits the maximum speed which may be varied by raising or lowering the tube 22 by a hand knob 34. When the solenoid is energized an arm 39 and a tube 37 are depressed and compress a second spring 35 of greater stiffness than the governor spring 19 which thereby lowers the seat 23 and increases the loading of the governor spring. For test purposes the tube 37 may also be depressed by a hand knob 82. The torque transmitter may alternatively be of the " Fottinger " hydraulic type.

[Class 78 (i)] [See also Group XXII] Material passed through a rolling mill 1 is received by a system of conveyers and passes from one conveyer to another until it is redelivered to the front of the rolls for another pass. As shown, the material is received by endless conveyers 9 and 19, the conveyer 19 then being automatically pivoted downwards about its end 12 to lower the material on to an oppositely moving endless conveyer 28 which forces it to an aligned conveyer 39 which passes it back over the top of the rolls whence it slides down a guide 50 to the feeding-in conveyer 3 for another pass. In passing to the first conveyer 9, the material actuates a switch 51 which pivots upwards the conveyer 19 into alignment with it, the switch 51 operating the motor 27 driving the crank 25 of the conveyer rod 24. When the material reaches the switch 52 on the conveyer 19 it similarly actuates the motor 27 to lower it about the pivot 12 and so transfer the work as above. All the conveyers are driven continually from a motor shaft 14, and all are mounted on a trolley 17 on rails 38. The space between the conveyer 28 and 39 is bridged by a connector 46.

Title: Machines for shearing webs of rubber incorporating longitudinally extending wires
IPC: B23D19/02
Filed: 1971-01-22
Abstract: 1350932 Shearing G GAZUIT 13 May 1971 [22 Jan 1971] 14866/71 Heading B3W A rubber web having longitudinally extending wires embedded therein is fed to a shear device 2 to be bias cut along a roller feed table 1 by a magnetic draw bar 8. The bar is mounted on a chain-driven feed carriage 10 which runs between a fixed stop 19 and an adjustable stop 20, the setting of the stop 20 determining the length of web to be sheared. A clutch 16 is slipped briefly at the end of a predetermined stroke when the carriage engages either of the stops. The shear device 2 is pivoted to the table to allow the angle of the longitudinal axis of the device, and thus of the shear path of a reciprocable shear carriage 30, to the feed direction to be varied between 14 and 90 degrees. The draw bar 8 is pivoted to the carriage 10 at 11 so that the bar can be moved to lie edge to edge with the adjusted shear device. During a cutting stroke a freely rotatable disc cutter 32 is urged by springs 38 against a fixed blade 33 and a series of fluid-actuated hold-downs 29 clamp the web to the upper face of blade 33. Spring balance devices in the hold-down mountings to compensate for variations in the thickness of the web. The disc cutter shaft 39 is eccentrically mounted in a cylinder 35 linked by tenons 40 to provide lost motion. The cylinders are rotatably mounted in a sleeve 31 which is adjustable in a horizontal plane to incline the cutter 32 slightly to the blade 33. The cylinder 34 is threaded on a fixed screw 36 and a roller 46 on the sleeve 31 engages in a helical groove 45 in the cylinder 35. A lever 41 fixed to the cylinder 34 engages a roller 42a fixed to a sleeve 42b slidably mounted on a bar 42. The carriage 30 and the bar 42 are reciprocable between end stops, the arrangement being such that the bar 42 engages its stop just before the carriage engages its stop, the carriage 30, during the final part of its stroke, driving the sleeve 42b along the bar and through the roller 42a, pivoting the lever 41 and therefore the cylinders 34, 35 through 90 degrees. Thus, at the end of a cutting stroke of carriage 30, the cylinder 34 is threaded along the screw 36 to the left, which relieves the pressure of springs 38 on the cutter 32, and the cylinder 35, due to the helical grooves 45 and roller 46, is moved to the left, which withdraws the cutter from engagement with the cutter 33 and, due to the eccentric mounting of the shaft 39, raises the cutter 32 clear of the cutter 33. Fluid-operated strippers (43), Fig. 6 (not shown), free the web from the blade 33. The reverse actions occur at the end of the carriage return stroke. While the carriage is returning, the sheared web strip is fed by a conveyer (3), Fig. 1 (not shown), to a station (4) at which it is joined to the preceding strip and a trimming station (5) before being coiled at station (6), and fresh web is fed to the cutters to an extent determined by the position of the stop 20.
